4,4',4'',4'''-(Pyrene-1,3,6,8-tetrayl)tetraaniline, CAS number 1610471-69-6, is a tecton fluorescent probe linker with four aniline side arms extending the pyrene core at 1,3,6,8-positions.

The introduction of flexible sulfonic acid groups on the channel walls of 2D covalent organic framework PyTTA–DHTA-COF, acquired by the condensation of 4,4′,4′′,4′′′-(pyrene-1,3,6,8-tetrayl)tetraaniline and 2,5-dihydroxyterephthalaldehyde, enhanced intrinsic proton conductivity up to 10⁻³ S cm⁻¹ at 25 °C and 100% relative humidity (RH) and high conductivity up to 10⁻² S cm⁻¹ at 70 °C and 100% RH without the introduction of any non-covalent acid molecules or imidazole derivatives.

Ultra-stable luminescent covalent organic framework PyTA-BC-Ph-COF, constructed through [4 + 4] condensation of 4,4′,4″,4′″-(pyrene-1,3,6,8-tetrayl)tetraaniline (PyTA-4NH2) with carbazole-based derivative, showed ultrahigh thermal stabilities, excellent crystallinity, and high BET surface area of 1445 m² g⁻¹. PyTA-BC-Ph-COF exhibited strong fluorescence emissions in various solvents, with their emission maxima gradually red-shifting upon increasing the polarity of the solvent. PyTA-BC-Ph-COF in ascorbic acid demonstrated a photocatalytic H₂ production of up to 1183 µmol g⁻¹ h⁻¹ even in the absence of noble metal cocatalyst,

Another 2D covalent organic framework, obtained from the electron-rich 4,4',4'',4'''-(Pyrene-1,3,6,8-Tetrayl)tetraaniline and electron-deficient 4,4'-(thiazolo[5,4-d]thiazole-2,5-diyl)dibenzaldehyde, exhibited a photocurrent up to 100 μA cm⁻² at 0.2 V vs. RHE and could reach a hydrogen evolution rate of 2072.4 μmol g⁻¹ h⁻¹.
