Abstract
Controlling the color via temperature-induced changes of self-assembled photonic materials is important for their application in sensors and displays. The thermochromic behavior of a PS-P2VP photonic gel was studied (UV-VIS, FTIR) and found to originate from a temperature-induced change in the pKa of the P2VP blocks in different acetic acid-water solutions. Control of the thermochromic response was obtained through the manipulation of the solution pH.Citation
