From Arylamines to Strongly Polarized Multiple Azahelicences: A Fascinating Journey

A straightforward route to strongly polarized multiple azahelicences comprising pyrrolo[۳,۲-b]pyrroleand two electron-withdrawing quinoline or tetrazolo[۱,۵-a]quinoline moieties has been developed. All thesequadrupolar hybrid dyes demonstrate fluorescence emission and display strong solvatofluorochromic effects.Interestingly, the pyrrolo[۳,۲-b]pyrrole dyes, containing fused tetrazoloquinoline sub-units, have achieved animpressive fluorescence quantum yield of an incredible ۱.۰ (۱۰۰%) in dichloromethane
