Main observation and conclusion In the present work,an artificial light-harvesting system with fluorescence resonance energy transfer(FRET)is successfully fabricated in aqueous sodium dodecyl sulfonate(SDS)micellar *** the tight and orderly arrangement of dodecyl in the SDS micelles is hydrophobic,tetra-(4-pyridylphenyl)ethylene(4PyTPE)can be easily encapsulated into the hydrophobic layer of SDS micelles through noncovalent interaction,which exhibits aggregation-induced emission(AIE)phenomenon and can be used as energy *** using amphoteric sulforhodamine 101(SR101)fluorescent dye attached to the negatively charged surface of SDS micelles through electrostatic interaction as energy acceptor,the light-harvesting FRET process can be efficiently *** the steady-state emission spectra analysis in the micelle-mediated energy transfer from 4PyTPE to SR101,the fluorescence emission can be tuned and white light emission with CIE coordinates of(0.31,0.29)can be successfully achieved by tuning the donor/acceptor *** importantly,to better mimic natural photosynthesis,the SDS micelles with 4PyTPE and SR101 FRET system showed enhanced catalytic activity in photochemical catalysis for dehalogenation ofα-bromoacetophenone in aqueous solution and the photocatalytic reaction could be extended to gram levels.

价值增殖既是资本的生命支点,又是资本加速的根本肇因。资本主导下的现代科技和现代机器不断加速商品生产、商品流通和商品消费,有限的生态承载力无法协同资本加速,因而造成“去同步化”的生态危机。严重的生态危机呼吁人与自然生命共同体关系的建构。“人与自然是生命共同体”论断包含丰富的生态意蕴,它蕴含着人与自然的生命共同体样态、人与自然的生命共同体意识、人与人的生命共同体理念。“人与自然是生命共同体”论断增强了马克思生态思想的时代生命力、助推了人与自然和谐共生的中国式现代化、贡献了解决全球生态危机的中国方案。“人与自然是生命共同体”论断对系统把握马克思生态思想,建构美丽中国、美丽世界具有重要意义。
