“…However, it did not significantly alter its absorption profile (684 nm (logϵ=3.86 mol L −1 cm −1 ) and 392 nm (logϵ=3.92 mol L −1 cm −1 )) in H 2 O. The spectra recorded in different solvents showed a slight shift in the CLCT band, compatible with solvent effects through interactions with the amino group [33] …”

“…The spectra recorded in different solvents showed a slight shift in the CLCT band, compatible with solvent effects through interactions with the amino group. [33] Due to the presence of the 4-ampy ligands in compound 1, we inferred the formation of hydrogen bonds between cluster units and between cluster units and crystallization water molecules involving the NH 2 group. Infrared spectroscopy (IR) provided the first indication of such occurrence (Figure SI3 shows the IR spectrum of 1, and Table SI2 lists the assignments of the main vibrations observed in the spectrum).…”

“…Dentro da química de coordenação, um dos motivos do estudo do efeito solvatocrômico em moléculas é verificar a influência da troca de ligantes na estrutura eletrônica do composto em questão, visto que as propriedades químicas desse composto estão diretamente ligadas a essa estrutura. Dadas todas as possíveis transições eletrônicas passíveis de ocorrer em um complexo de coordenação, as transições de transferência de carga são especialmente sensíveis à mudança do solvente, visto que essas transições essencialmente geram uma separação de cargas no composto de coordenação, tornando a energia dos estados envolvidos na transição muito dependente da polaridade do ambiente químico ao qual se encontram (BALZANI;CERONI;JURIS, 2014;CIONCOLONI et al, 2016;PEREZ et al, 2021).…”
