A novel conjugated organic molecule based on central phenothiazine unit as an electronic donor and aldehyde group termini as an electronic acceptor has been designed and constructed. Optical spectra show that, the absorption and fluorescence spectra of M2 are large red-shifted relative to M1 in both states, however, from solution to the solid state, the absorption maxima and emission maxima of M1 and M2 are in the opposite trends (blue-shift). The fluorescence spectra exhibit that the emission maxima of M1 and M2 which range from 485 nm to 588 nm belong to green light region. As expected, the target compounds should be a promising green light-emitting material for applications in organic light-emitting diodes (OLEDs).
设计并构建了一种基于中心苯噻嗪单元作为电子供体和醛基末端作为电子受体的新型共轭有机分子。光学光谱显示,M2的吸收光谱和荧光光谱相对于M1在两种状态下均大幅红移,然而,从溶液到固态,M1和M2的吸收峰值和发射峰值呈现相反的趋势(蓝移)。荧光光谱显示,M1和M2的发射峰值范围从485 nm到588 nm,属于绿色光区域。正如预期的那样,目标化合物应成为有机发光二极管(OLEDs)应用中一种有前景的绿色光发射材料。
