Utilization of solar heat radiation into chemical energy is attributed to semiconductor photocatalyst under sunlight perspective considered as a reversing inspired approach that exacerbates the environmental problems. Recently, our group indicates graphitic carbon nitride (g-CN) by a progressive molecular aggregation co-polymerization process that propagated with a nanoscopic organic conjugated heterocyclic

Forerunner investigators of photocatalysis utilized TiO2 as the photocatalyst of choice. It has major drawbacks of which the most important one is that it is only activated under ultraviolet (UV) light irradiation. This high energy consumption made the process practically unfeasible. Solar energy (natural light and heat from sun) has great prospects with regards to acting as a substitute for UV light

The new benzimidazole ligands (3a-e) were synthesized using ethyl 4-(butylamino)-3-nitrobenzoate and substituted salicylaldehyde in the presence of sodium dithionite reagent which undergoes “one-pot’’ nitro reductive cyclization. Here benzimidazole moiety acts as an electron-acceptor (A) whereas substituted 2-hydroxyphenyl moiety acts as an electron-donor (D) unit. The molecular structures were characterised

Photoinduced charge carrier dynamics studies in lead halide perovskites helps in explaining key processes like carrier trapping, diffusion and multiexciton dynamics etc. which are of importance to understand the fate of excitons. In the present study, we investigate the dynamics in methylammonium lead bromide perovskite nanocrystals under low and high pump intensity to study hot carrier cooling mechanisms

Binol-pyrene conjugate (BPC), as fluorescent probe was synthesized by multi-step synthetic strategies. BPC acts as a single sensor for dual analyte detection by a turn “on-off” mechanism for Ag+ and CO32− ions. In the emission spectra, the monomer peaks of BPC were drastically quenched by the addition of Ag+ and CO32− ions, due to the reverse photo-induced electron transfer (PET) process, excited-state

Three ternary complexes featuring Eu3+ have been prepared by using primary ligand Kojic acid and secondary ligands 4-methyl-110-phenanthroline; 3,4,7,8-tetramethyl-110-phenanthroline and bathocuproine. Characterization of synthesized complexes was carried out using spectroscopic techniques: FTIR, elemental analysis, ESI-MS+, UV, TGA, FESEM, P-XRD, and Photoluminescence studies (PL). Results of P-XRD

A chemical sensor composed of pyridoxal hydrochloride schiff base based on diarylethene (1O) was synthesized. Its photochemical properties and selectivity to ions were further studied. The chemosensor could detect cyanide effectively and is almost undisturbed by other ions. When titrating CN−, the reaction aroused a distinct change in the absorption spectrum with the color change from transparent to

Content of adenosine triphosphate (ATP) is an essential index in the development of various diseases and even some malignant tumors. Biosensing for ATP with high sensitivity and accuracy is of fundamental importance in both biological research and medical diagnostics. Here we report a ratiometric fluorescent sensor for ATP based on multi-color silver nanoclusters (Ag NCs). This nanosystem contains
