Problems solved by technology

But the fly in the ointment is that the conformational instability of monoethyl bridged sulfonated calix[4]arene can be flipped, so the formed supramolecular polymers are easy to agglomerate, resulting in poor water solubility.

Abstract

The invention relates to a supramolecular polymer material constructed by doubly bridging sulfonated calixarenes. The chemical formula of a repetitive unit is C88H78N4O34S8, which is formed by dual-ethyl bridging sulfonated calix [4] arene (bisSC4A*8Na+) and diethylene three ether oxygen chain bridging methyl viologen (bisMV4+*4I-), wherein the bisSC4A is taken as a large ring host body, the bisMV4+ is taken as a guest body, and the supramolecular polymer with a host-guest inclusion structure is constructed through host-guest bonding. The invention has the advantages that the polymer material can be prepared by utilizing strong bonding of sulfonated calixarenes to the viologen guest body through a simple and convenient solution mixing method; and the method has the advantages of simplicity in operation and high productivity, is a convenient and effective method for preparing the polymer material and can detect the formation of supramolecular polymer through fluorescence, can effectively improve the water solubility and viscosity of calixarene class supramolecular polymer at the same time, and has a broad application prospect in the field of materials.

Description

【Technical field】 [0001] The invention relates to a preparation technology of a supramolecular polymer material, in particular to a supramolecular polymer material constructed of double-bridged sulfonated calixarene and its preparation. 【Background technique】 [0002] Supramolecular polymers are a new class of materials constructed through non-covalent bond interactions that have both supramolecular chemical properties and polymer material properties, see: 1) Brunsveld, L., Folmer, B.J.B., Meijer, E.W. , Sijbesma, R.P.Chem.Rev.2001, 101, 4071-4097.2) Guo, D.-S., Liu, Y.Chem.Soc.Rev., 2012, 41, 5907–5921. Supramolecular polymers can be formed based on various intermolecular interactions and their synergistic or multiple interactions, such as hydrogen bonding, coordination, host-guest interactions, charge-transfer interactions, π-π interactions, etc. Supramolecular polymers are responsive to external stimuli. Compared with covalent polymer molecules, supramolecular polymers h...
