Photocatalysts are typically employed as nanoparticles dispersed in water, making interactions with surrounding water molecules a key factor in photophysical studies. In fact, long-lived charge carriers are observed in nanoparticles but not in thin films, and this may be due to surrounding water, yet the detailed mechanism remains unclear. In this study, we focus on the specific surface area and investigate how water affects charge carrier dynamics within the system. To this end, we prepare films of 35 nm (high specific surface area) and 130 nm (bulk-like) thickness, and compare the effects of water on charge carrier dynamics in these systems using transient absorption spectroscopy. We find that water prolongs the lifetime of charge carriers in 35 nm films, whereas its effect is negligible in 130 nm films. This result suggests that the impact of water is confined to the surface rather than being widespread over the entire film. We therefore conclude that only the charge carriers near the surface of thin films or nanoparticles have prolonged lifetimes due to the influence of the surrounding water.</p>\u0000 </div>","PeriodicalId":18054,"journal":{"name":"Macromolecular Chemistry and Physics","volume":"227 8","pages":""},"PeriodicalIF":2.7,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147686046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A labeling with maximum contrast between both types of polymers is most suitable for determining the onset of the nano-phase separation. Labeling only the phase separated domains provides the clearest information on the statistics of the clusters, leading to a pronounced peak in the scattering intensity. For nearly spherical domains, analyzing peak height and domain spacing allows to determine the aggregation number of the domains. Our analysis shows that the nano-phase separated star polymer co-networks can be understood as a set of connected micelles where the statistics of the micelles and their connections encodes the different elastic properties.

Minor glycidyloxypropyltrimethoxysilane (GPTOS) along with major tetraethoxysilane (TEOS) is dispersed in water with the aid of a supramolecular emulsifier of PEI/sodium dodecylbenzene sulfonate (SDBS), and the resulting emulsion directly affords open, PEI-dictated and 3D macroporous silica after standing and subsequent vacuum drying.
