The invention provides a triphenylamine-based dithieno-pyrrole compound containing carbazole, a preparation method of the compound, a polymer as well as a preparation method and an application of the polymer, relates to a pyrrole compound, a preparation method thereof, the polymer as well as the preparation method and the application of the polymer and aims at solving the problems of poor film-forming property and single color-change property of an existing electrochromic polymer. The compound has a structural formula (shown in the specification) and is prepared by the steps of adding 2,5-bis (2-thienyl)-1,4-butanedione monomer, N,N-bis(4-carbazol-phenyl)-N,N-diphenyl-1,4-phenylenediamine and p-toluenesulfonic acid into toluene, and carrying out heating reflux and rotary evaporateion. The polymer has a structural formula (shown in the specification) and is prepared by the step of polymerizing the compound. The polymer is used as a multifunctional organic polymer to be applied to electrochromic materials, photoelectronic devices or biosensors. According to the preparation method, the triphenylamine-based dithieno-pyrrole polymer can be obtained.
