This paper presents a new concept of molecular communication that mimics the operations of some specific semiconductor based electronic devices. In this report, one molecule N,N '‐bis(salicyaldehydene)‐1,3‐diaminopropan‐2‐ol (2‐IMP) acted as sender while a similar analog 2,2 ′‐(( 1E,1′E )‐(1,2‐phenylenebis(methanylylidene))bis(azanylylidene))diphenol)) (hereafter PMP) molecule played the role of a receiver. 2‐IMP and PMP were designed, synthesized and then employed for the transportation of an information molecule, Zn(AcO) 2 (ZA) after its selective detection and capturing from diversely crowded conditions. Upon exposure of 2‐IMP toward a diversified mixture, excluding the presence of Cu II only, revealed a highly selective optical response for ZA at nanomolar sensitivity level. These were evidenced by significant changes in the absorption spectra and extensive consecutive rise and fall in emission intensity of 2‐IMP. Interestingly, the stepwise loading‐transporting‐unloading process was fully autonomous and did not require any external control. Therefore, this molecular machine might find promising applications in controllable molecular transport and release. They are of great importance in designing of next generation molecular devices.
