Computed Properties of C27H18AlN3O3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate.

It has been demonstrated that organic semiconductor micro-/nanocrystals with multicolor emission/waveguide characterizations would be widely utilized as ideal building blocks for the next generation of miniaturized optical, electronic and logic operation devices. However, rational synthesis of one dimensional micro-/nanocrystals with multicolor emission and optical waveguide performances are highly desirable and still remain a challenge. Here, the DCM doped Alq3 single-crystalline microrods are fabricated via a facile solution-exchange method. It is found that a red shift in light-emission frequency is extremely sensitive to the doping concentration of 4-(dicyano-methylene)-2-methyl-6-(4-dimethylamino-styryl)-4Hpyran (DCM) guest mol. The green emission at 527 nm of Alq3 is the main emitting peak when doping concentration of DCM in Alq3:DCM is less than 150:1. Then, when the doping concentration of DCM in Alq3:DCM is larger than 100:2 such as 100:10, the red emission at 635 nm becomes the dominant emitting peak, the red shift amounts can reach to roughly 108 nm. In addition, the DCM-doped Alq3 microrods exhibit a lower optical loss of 0.019 dB/μm as a multicolored waveguide material. Therefore, it is demonstrated that the DCM-doped organic micro/nano crystals can be utilized as a promising building block for various optoelectronic components.
