Liquid− and solid−state study of charge-transfer (CT) interaction between drug triamterene as a donor and tetracyanoethylene (TCNE) as an acceptor

In this work, the liquid–liquid and solid–solid charge-transfer (CT) interactions of drug triamterene (TA) with tetracyanoethylene (TCNE) were reported. The soluble TA-TCNE CT complex was easily generated by mixing acetonitrile solution of TA as the donor and TCNE as the acceptor at room temperature. The solid TA-TCNE CT complex was easily generated by grinding equimolar amounts of TA and TCNE in powder form without any solvent. The results...
