Embodiment 1

[0034] The preparation method of microporous ladder polymer (PAnTB) in the present invention comprises the following steps:

[0035] (1) Add bisanthracene monomer (AnTB) (50mg) into chlorobenzene (10mL) at a monomer concentration of (5mg / mL), stir well until completely dissolved. The synthetic method of double anthracene monomer (AnTB) is prior art, can refer to: (A.Tatar et al.Org.Lett.2010,12,1872; M.Havlik et al.Collect.Czech.Chem.Commun.2007, 72,392).

Description

technical field [0001] The invention belongs to the field of high molecular polymers, and more specifically relates to a microporous ladder polymer and its synthesis method and application. Background technique [0002] Compared with single-chain linear polymers, ladder polymers have higher chemical / thermal stability, excellent optoelectronic properties and restricted conformational rotation due to the fact that the two main chains are connected by covalent bonds. Therefore, ladder polymers have attracted much attention due to their remarkable applications in the fields of nonlinear optical materials, OLED optoelectronic devices, and separation membranes. [0003] At present, the synthesis of ladder polymers mainly includes direct polycondensation method and post-ring closure method. The direct polycondensation method realizes stepwise polymerization through the efficient reaction of multifunctional monomers to obtain ladder polymers. The ring-closing method is to obtain a...
