WebDec 24, 2024 · Three cross-conjugated chalcone derivatives T3CT, T3CP2, and T3CP3 were designed and synthesized to develop excellent organic nonlinear optical (NLO) materials. In a Z-scan experiment, all compounds show good NLO absorption characteristics in the visible to near-infrared region. The photophysical mechanism is confirmed to be … WebApr 4, 2024 · We define six different bridge structures with linearly conjugated, cross-conjugated, and saturated bonds. We calculate electron transport properties to obtain the current-voltage I–Vcharacteristics and rectification ratios (R) at low bias voltages.

WebJan 16, 2024 · The cross-conjugated vinylogous [4+2] anionic annulation has been newly developed, the cascade process of which has a high preference for regiochemical control and chemoselectivity, giving rise to exclusively Michael-type adducts in moderate to high yields (up to 94 %, 35 examples). WebUntil very recently, this form of conjugation, in which two separate conjugated branches are linked to the same carbon atom which is part of a (shared) double bond, was considered to be much less able to promote electron delocalization than through-conjugation. men\u0027s v-neck pima cotton jersey t-shirt
