NOVELTY - Method for synthesizing a porphyrin conjugated polymer bridged by a pincer complex involves (a) adding 5,10,15,20-tetrakis(4-formylphenyl)porphyrin or its copper complex (I) and 2,6-bis(5-amino-1H-benzimidazolyl)pyridine or its ruthenium pincer complex to an o-dichlorobenzene-n-butanol mixed solvent to dissolve, (b) adding catalyst to the reaction mixture, carrying out freezing-vacuum-thaw cycle, and sealing the tube flame to complete the reaction, and (c) filtering the product, washing and extracting to obtain a conjugated polymer. USE - The method is useful for synthesizing a porphyrin conjugated polymer. ADVANTAGE - The polymer improves intrinsic conductivity and adsorption of water molecules, accelerates electron transfer between copper and ruthenium metal center, and improves electrocatalytic hydrogen evolution performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for synthesizing a copper porphyrin conjugated polymer bridged by a ruthenium pincer complex involving carrying out the above-mentioned steps (a)-(c); and (2) a use of copper porphyrin conjugated polymer bridged by a ruthenium pincer complex synthesized as a universal hydrogen evolution electrocatalytic material in a full pH range involving adding the mixture of copper porphyrin conjugated polymer bridged by the ruthenium pincer complex and graphene oxide to Nafion (RTM: polymer electrolyte membrane material giving polymer electrolyte membrane fuel cells) ethanol solution, ultrasonically dispersing to obtain a uniform suspension, dripping uniformly on the carbon cloth after drying to use as a working electrode, and using silver/silver chloride as a reference electrode and a graphite rod as a counter electrode, which is used as a universal electrocatalytic material for hydrogen evolution within the full pH range.
