“…Compared with colorless PIs, the successful incorporation of PTCDA (red PIs) and PDA (blue PIs) was evidenced by the gradual emergence of an absorption peak at ≈1644 cm −1 , corresponding to the characteristic stretching vibration of C═O of perylene imide ring. [ 33 ] The characteristic stretching vibration of C═O in AHAQ was at around ≈1566 cm −1 , [ 34 ] but it was not obvious in the IR spectrum of purple PIs because only small amount of AHAQ monomer was incorporated. Since the azo unit (─N═N─) in chrysoidin itself exhibited weak absorption in FTIR, the characteristic absorption peaks of yellow PIs were not significant.…”

A versatile strategy of preparing colored polyimide (PI) films was developed by embedding colored monomers on the backbones of colorless substrate polymers. Intrinsically colored PI films of four colors – red, yellow, blue and purple, were prepared by introducing relative chromophores to the substrate PI that were synthesized from TFMB and 6FDA – two widely‐used monomers for colorless and transparent PI films. In addition, a series of orange and green PI films have been prepared by simple mixing of the red, yellow or blue PIs. The properties of these colored PI films were characterized, exhibiting good mechanical, thermal and solubility properties, as well as different color and brightness depending on the amounts and types of chromophores. The optical properties of these films were determined by UV‐vis spectroscopy and CIE LAB. It was demonstrated that the introduction of even small amounts of chromophores can afford spectrally colored films while maintaining the original benign properties of the substrate PIs.This article is protected by copyright.

“…MOF Cr-PTC pernah disintesis untuk fotodegradasi metilen biru [14]. Co(II) pun pernah pernah menjadi prekursor logam dengan PTC namun dalam bentuk anhidridanya (PTCDA) sehingga membentuk material MOF untuk dianalisis sifat flurosensinya [15]. Sampai saat ini belum ada penelitian tentang sintesis dan karakterisasi MOF berbasis logam Fe(III) dan ligan PTC beserta aplikasinya dalam bidang fotodegaradasi.…”

Metilen biru merupakan salah satu zat warna yang sangat sulit terdegradasi dan mengganggu ekosistem perairan. Metal Organic Framework (MOF) merupakan kelompok material yang dapat bertindak sebagai fotokatalis untuk mendegradasi zat warna di bawah cahaya tampak. Penelitian ini bertujuan untuk mensintesis material MOF baru menggunakan logam besi (Fe) dan penghubung organik perylene-3,4,9,10-tetracarboxylate (PTC) melalui metode solvotermal pada suhu 170 o C selama 24 jam, lalu dikarakterisasi menggunakan FTIR, XRD, DRS, dan SEM-EDS, serta aplikasinya dalam menentukan kondisi optimum dari fotodegradasi zat warna metilen biru oleh MOF Fe-PTC dengan penambahan H2O2 menggunakan desain box behnken. Indikasi keberhasilan sintesis MOF Fe-PTC ditunjukkan oleh beberapa karakterisasi yaitu (1) spektrum FTIR dengan serapan pada bilangan gelombang 572 cm -1 yang mengidentifikasi keberadaan ikatan antara Fe dan O, (2) uji kelarutan yang menunjukkan material sukar larut dalam pelarut polar, semipolar, dan nonpolar, serta (3) EDS Mapping yang menunjukkan keberadaan unsur Fe dengan persentase bobot sebesar 21,6%. MOF Fe-PTC hasil sintesis memiliki derajat kristalinitas sebesar 46,56% dan rata-rata ukuran kristal sebesar 50,9 nm dengan puncak difraksi tertinggi pada 2θ = 33.16°. Analisis DRS menunjukkan bahwa MOF Fe-PTC mempunyai energi bandgap sebesar 1,93 eV dengan panjang gelombang maksimum (max) sebesar 638 nm. Karakterisasi menggunakan SEM menunjukkan bahwa MOF Fe-PTC mempunyai bentuk seperti tabung silinder. Kondisi optimum yang diperoleh dari fotodegradasi metilen biru oleh MOF Fe-PTC dengan penambahan H2O2 di bawah iradiasi cahaya tampak sebesar 250 W secara statistik adalah 1,35 mg untuk bobot fotokatalis, 0,22 M untuk konsentrasi H2O2, dan 135 menit untuk waktu kontak.
