A series of indolenine-based croconaines has been synthesized and their molecular structure has been investigated together with their solid state organization. Ambipolar semiconducting properties have been demonstrated in thin-film transistors, suggesting croconaines as a new class of molecular materials for organic electronics. Indolenine-based croconaines are synthesized, their structure and solid state organization are investigated together with their electronic properties in thin-film transistors.
