Lone pairs are essential for exploring the mechanism behind the phenomena in the areas of opto-spintronics. In this paper, the effect of lone pairs on spin resonance and magnetic properties was studied. Using donors with different nitrogen substitutions, three charge transfer crystals were fabricated. In cocrystals, lone pairs could enlarge the distance between donors and acceptors, leading to the shorten of lifetime and the decrease of dielectric constant. Moreover, lone pairs possess the ability to enhance spin-lattice interactions, enabling the three crystals to display diverse and intriguing behaviors under light and magnetic fields, such as light-dependent electron spin resonance.
