분자 태양열 시스템은 특수 분자의 가역적인 광이성질화 반응을 통해 태양 에너지를 활용하고 저장합니다.

분자 태양열(MOST) 시스템은 광전환 가능한 분자, 특히 노르보르나디엔-쿼드리시클란 쌍의 화학 결합 내에 태양 에너지를 직접 저장하며, 이는 가역적인 광이성질화 반응을 통해 이루어집니다. 입사광자는 분자를 안정적인 바닥 상태에서 변형된 상태로 전환시킵니다. 고에너지 원자가 이성질체는 촉매 작용으로 역반응이 시작되어 필요에 따라 열을 방출할 때까지 잠재적으로 수개월 동안 저장된 에너지를 유지합니다.

시스템 성능은 양자 수율, 태양 스펙트럼과 일치하는 몰 소멸 계수, 분자당 에너지 밀도, 역 이성질화 반응의 활성화 에너지 장벽, 그리고 반복적인 사이클에 걸친 장기적인 피로 저항성에 따라 달라집니다. 치환기 조절 및 공액 연결기를 통한 분자 기능화, 연속 흐름 광반응기, 그리고 DFT 기반 설계는 현재 연구의 최전선을 정의합니다.

Method for making methylene dianiline and polymethylene polyanilines using sapo-18 molecular sieve

Patent published on the 2026-06-18 in WO under Ref WO2026128799 by DOW GLOBAL TECH LLC [US] (Steelman David Keith [us], Barton David G [us], Wang Hongyi [us], Chojecki Adam [nl])

Abstract: Mixtures of methylene dianiline isomers and polymethylene polyanilines are made with controllable methylene dianiline isomer ratios. Aniline and formaldehyde are reacted to produce N,N -diphenylmethylene diamine (aminal), which is then partially rearranged to a mixture of aminobenzyl aniline isomers and methylene dianiline isomers in the presence of a SAPO-18 molecular sieve. Further rearrangement may be performed in the presence of a homogeneous catalyst to convert the remaining aminobenzyl ani[...]


Our summary: The method involves producing methylene dianiline and polymethylene polyanilines using a SAPO-18 molecular sieve. Methylene dianiline isomer ratios can be controlled through the reaction of aniline and formaldehyde. Further rearrangement with a homogeneous catalyst converts remaining isomers to the desired products.

Abstract: Metallaphotoredox catalysis merges the powerful bond-forming abilities of transition metal catalysis with unique electron or energy transfer pathways accessible in photoexcited states, injecting new vitality into organic synthesis. However, most transition metal catalysts cannot be excited by visible light. Thus, prevalent metallaphotoredox catalytic systems require dual catalysts: a transition metal catalyst and a separate photosensitizer. This leads to inefficient electron transfer between the[...]
