A tetraphenylethylene-based covalent organic polymer for highly selective and sensitive detection of Fe3+ and as a white light emitting diode

A newly prepared tetraphenylethylene-based (TPE-based) covalent organic polymer (COP) named COP-1 exhibites high selectivity of Fe3+ sensor and limit of detection (LOD) of the Fe3+ is 0.42 µM, which is lower than the reported metal-free porous polymers. Furthermore, a WLED is fabricated with CIE coordinate is (0.32, 0.33) very close to pure white light. The COP-1 shows the potential application in biosensors of Fe3+ and preparation of WLEDs.
