Synthesis of rhodamine chemosensors with high selectivity and sensitivity for multiple metal ions detection / Nur Amira Solehah Pungut

Four rhodamine B based chemosensors have been synthesized through condensation reaction between rhodamine B hydrazide with 2-hydroxy-3-methoxybenzaldehyde (RBOV), fluorene-2-carboxaldehyde (RFC), trans-4-(Diethylamino)cinnamaldehyde (RT4) and 3,4,5-trimethoxybenzaldehyde (R3). The compounds were cha...
