A photochemical logic gate is based on the photochemical intersystem crossing and molecular electronic transition between photochemically active molecules, leading to logic gates that can be produced. ==The OR gate electron–photon transfer chain== _A * A * = excited state of molecule A _B * _C * _A _B _C The OR gate is based on the activation of molecule A, and thus pass electron / photon to molecule C’s excited state orbitals ( C *). The electron from molecule A inter system crosses to C * via the excited state orbitals of B, eventually utilised as a signal in the C * h emission. The ‘OR’ gate uses two inputs of light (photons) to molecule A in two separate electron transfer chains, both of which are capable of transferring to C * and thus producing the output of an OR gate. Therefore, if either electron transfer chain is activated, molecule C’s excitation produces a valid/ output emission.
