A comparative photophysicochemical study of phthalocyanines encapsulated in core–shell silica nanoparticles

Nonlinear optical response of tetra and mono substituted zinc phthalocyanine complexes

“…The increase in the population of the triplet state as a result of the presence of a high molecular weight element is known as the heavy atom effect, the process occurs as a consequence of the spin orbit coupling. The syntheses of complexes 4, 5, 6, 7, 8 and 9 have been reported before [20][21][22][23][24][25] 2. EXPERIMENTAL…”
