• +1.6 V vs. saturated calomel electrode (SCE). These observations, together with UV–vis spectra, suggest the absence of intramolecular charge transfer in the ground state for dyads 2a–d. Preliminary investigation of the dyads 2a–d by polarized optical microscopy (POM) showed that the length of the
