4',4''',4''''',4'''''''-(Ethene-1,1,2,2-tetrayl)tetrakis(([1,1'-biphenyl]-4-carbaldehyde)) (TABPE) is structurally consisted of four 1,1'-biphenyl-4-carbaldehyde that are connected by an ethene double bond.
Full sp2-carbon skeleton connected through vinylidene linkages, conjugated porous polymer TPT-CMP obtained by acid-catalysed Knoevenagel condensation of ethene-1,1,2,2-tetrayl-tetrakis-1,1′-biphenyl-4-carbaldehyde with s-indacene-1,3,5,7-(2H,6H)-tetraone, demonstrates a high capacity of 550 mA h g−1 at 100 mA g−1 as the anode together with carbon nanotubes. The composite electrode shows great stability sustaining 500 cycles without great loss of its capacity.

By using 2,2'-(1,4-phenylene)diacetonitrile and 4′,4‴,4‴'',4‴''''-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1′-biphenyl]-4-carbaldehyde)) as building blocks, sp2-carbon-linked covalent organic framework (COF) can be obtained. The COF emits bright yellow light with a solid-state photoluminescence quantum yield (PLQY) of 39.2%. When blended in epoxy resin at a concentration of 1.5 wt%, the COF phosphor gives cold WLED , with a colour rendering index (CRI) of 83.4, Commission Internationale de L'Eclairage (CIE) chromaticity coordinate of (0.32, 0.29), and luminous efficiency (ηL) of 20.31 lm·W−1.
Superhydrophobic ether-based porous organic polymer E-POP-1, prepared by the condensation of 4′,4‴,4‴″,4‴‴′’’’’-(ethene-1,1,2,2-tetrayl)tetrakis(([1,1′-biphenyl]-4-carbaldehyde)) and a pentaerythritol monomer, exhibits super hydrophobicity on account of abundant ether groups. While coated on the polyurethane as a sponge, E-POP-1@PU can rapidly and selectively adsorb various kinds of oils up to 82 times of its own weight, making it a great candidate for large-scale industrial separation of oils and water.
