Structures and transistor properties of extended and unsymmetrical birhodanines

Abstract

Birhodanines exhibit n-channel transistor properties with air stability. In this work, birhodanines with extended skeletons are investigated, in which a phenylene or quinoidal moiety is inserted in the central C=C...

n-Channel Transistor Properties of Fluoroalkyl and Trithione Form Birhodanines

“… ,, The corresponding OS-CH 2 CF 3 was not obtained following this route. For that purpose, we used a different synthetic strategy, route B in Scheme , which consisted of coupling of rhodanine 1 with isatin 2 , both of these heterocycles being substituted with the same R group ( R = CH 2 CF 3 ). We also prepared the unsymmetrically substituted derivatives, OS- RR ′ (route B) through the coupling of rhodanine 1 with isatin 2 , both of these heterocycles substituted with different substituents R ≠ R ′.…”
