Excited state iminium form can explain the unexpected solvatochromic behavior of symmetric 1,5- and 1,8-diaminonaphthalenes

Abstract

A new model based on the presence of excited state iminium ion (Ar=NH2+) is proposed to interpret the solvatochromic behavior of symmetric 1,5- and 1,8-diaminonaphtahelenes (DANs). The importance of using...
