Abstract
There are two parts of studies in the thesis, first one is the synthesis and applications of hole-transport material in perovskite solar cell, the second one is the synthesis and photophysical properties of Pt complexs as a phosphorescent emitter. In the first part, we have a common hole transport material spiro-OMeTAD based, synthesized three novel compounds CW3, CW4 and CW5, these compounds have a molecular weight of smaller, more efficient way of synthesis, as well as the good physical and chemical properties required hole transport material. The device efficiency of perovskite solar cell which was fabricated with compound CW4 as hole transport materials can reach 16.56%. In the second part, we introduce a strong-field carbene functional group to synthesize a novel series of platinum complexes, and measuring the photophysical properties. Light color can be tuned from the blue to orange light and several complexes having light quantum yield of more than 90%, while the lifetime from common dozens of microseconds (μs) success shortened to about 400 ~ 1000 ns. These platinum complexes have excellent potential as phosphorescent materials utilized in organic light emitting diodes.
