A series of organic NIR third-order NLO cyanine dyes were designed and synthesized using a Sonogashira coupling reaction and the high-yielding [2 + 2] click reaction. The photophysical and the click reactions were characterized by means of UV/Vis absorption spectroscopy. The electrochemical properties were characterized by means of cyclic voltammetry. In addition, the third-order nonlinear properties,...
The novel kind of charge-transfer porphyrin complexes with symmetrical and asymmetrical side groups were synthesized by the high-yielding [2 + 2] click chemistry reaction involved a two-step procedure. Both electrochemical and UV–vis studies were characterized and proved that the side groups of the porphyrin complexes played an important role on optical properties and energy gaps. The novel series...
