Such heterocyclic precursors and related dyes were identified by elemental and spectral analyses. The absorption spectra properties of such dyes were investigated in 95% Ethanol to attempt and throw some light on the influence of such new heterocyclic nuclei and to compare or evaluate spectral behaviors. The absorption spectra of dyes in different pure solvents were examined in the visible region showing solvatochromism and the colour changes of dyes with solvents having different polarities. This permits a selection of the optimal solvent (fractional solvent) when such dyes are applied as photosensitizers. The spectral behavior of some selected newly synthesized cyanine dyes is observed in mixed solvents of different polarities and progressively increasing quantities of one solvent over the other were studied and showed an increase in the absorbance of CT band with increasing proportion of that solvent. Evidence for hydrogen bond formation between the solute molecules and solvent molecules allows measurement of certain energies such as hydrogen bonding, orientation, and free energies.

The structure of the newly prepared heterocycles was determined using various spectral techniques such as MS, IR, NMR, and elemental analysis. The antibacterial activity of these compounds against Escherichia coli (E. coli) and Bacillus subtilis (B. subtilis) was evaluated, and it was found that all arylazo nicotinate compounds were highly effective against both gram-negative (E. coli) and gram-positive (B. subtilis) bacterial strains. The efficacy of the developed arylazo nicotinate derivatives as antimicrobial agents against E. coli and B. subtilis was evaluated using minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. Density-functional theory (DFT) was employed to investigate the structure-activity relationships of recently synthesized compounds. Gaussian 09 software

The synthesized compounds (3, 11 a-j) were characterized using via IR, 1 H-, 13 C-NMR, and MS spectroscopies as well as elemental analysis. The biological activity of these molecules has been evaluated in vitro against two grampositive bacteria (Staphylococcus aureus and Streptococcus pneumoniae) and one-gram negative bacteria (Escherichia coli), as well as one fungus (Candida albicans). The results of the bioactive assay revealed that the synthesized pyridine (11 a-j) derivatives had greater antibacterial efficacy than the hydrazide (3 a-j) derivatives and were comparable to the reference drug Augmentin. Furthermore, docking studies against the Staphylococcus aureus dihydrofolate reductase (DHFR) protein revealed that pyridine derivatives (11 a-j) had higher binding interactions affinity (ΔG = À 9.59 ∼ À 7.69 kcal/mol) than diphenylÀ malonohydrazide derivatives (3 a-j), which achieved a binding affinity in the range of (ΔG = À 9.65 ∼ À 6.77 kcal/ mol), supporting the experimental results. Finally, DFT and TD-DFT were used to gain a better understanding of the structureactivity relationship and biological activity of the new synthesized hydrazide/pyridine derivatives.

The fabricated perovskite solar cells (PSCs) utilizing these HTMs without any dopants under 1 sun illumination (100 mW cm−2, AM 1.5G) and surface area of 1.02 cm2 achieved a short circuit current (JSC = 19.23), open circuit voltage (VOC = 1.042), fill factor (FF = 0.679) and overall power conversion efficiency (PCE = 13.61%) for DBT(QT-TPA)2. While, T(EDOT-TPA)2 exhibited (JSC = 20.25, VOC = 1.04, FF = 0.583, and PCE = 12.27%). These dopant free HTM based PSCs achieved superior PCEs compared to that of undoped Spiro-OMeTAD (PCE = 9.34%) based PSCs and a comparable photovoltaic performance to the PSCs using doped Spiro-OMeTAD (JSC = 20.37, VOC = 1.057, FF = 0.74, and PCE = 15.93) as the HTM under same fabrication conditions. Noticeably, the absence of additives is of significant importance, as DBT(QT-TPA)2 and T(EDOT-TPA)2 based PSCs still produces a Jsc up to 20.25 mA cm−2 and a comparable PCE of 13.61%, which reduces the fabrication cost of cm sized PSCs.

These sensitizers are comprised of a phenyl ring as a donor scaffold connected with a carboxylic group as acceptor/anchoring unit. To gauge their applicability as photosensitizers for DSSCs the photophysical, electrochemical, theoretical studies and charge transport characteristics were carried out. Interestingly, uses of S 2 and S 4 dyes as co-sensitizers with well-known MH-13 dye resulted in enhancing its photovoltaic properties from 8.217 to 8.79% and 8.48%, respectively. Furthermore, the photo-sensitizer S 3 individually shows better photovoltaic properties compared to S 1 , S 2 and S 4 , due to the fast photo-induced electron transfer from the phenyl ring to the nitro group. This fast electron transfer resulted from the overlapping between HOMO and LUMO levels on phenyl ring bearing nitro group. The results indicate that these simple and easy prepared Schiff bases moieties may be considered as promising and low-cost co-sensitizers for DSSCs.

The newly designed IA 1-4 were applied as sensitizers and co-sensitizers in DSSCs. Their structures were confirmed by FT-IR, 1 H-NMR, MS and elemental analyses. The photosensitizers were subjected to optical and electrochemical studies in order to investigate their absorption/emission behavior as well as HOMO/LUMO energies. The UV-Vis revealed that IA 1-4 exhibited at 464, 497, 531 and 412 nm,λ max respectively. Their optical band gap is in the range of 1.95 to 2.28 eV. From the energy level diagram of the named photosensitizer, it is clear that all the dyes have good thermodynamically favorable ground and excited state oxidation potentials for electron injection into CB edge of TiO 2 as well as dye regeneration. The photovoltaic performance studies indicate that, dye IA-1 anchored with cyanoacetic acid displayed the highest IPCE (61.5%), resulting in PCE of 5.92 % (J SC = 12.3 mA cm-2 , V OC = 0.68 V, FF = 70.29 %). Furthermore, when IA-1 was used as a co-sensitizer with MH-13, a total PCE
