MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance
Advanced Functional Materials, EarlyView.Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Advanced Functional Materials, EarlyView.Spark plasma sintering enables rapid processing of porous organic polymer (POP) from fine powders to a freestanding and mechanically robust monolith. The sintering process retains the CO2 adsorption capacity and CO2/N2 selectivity, making the monolith more suitable as a solid sorbent for practical carbon capture applications.

Ultraweak Chemiluminescence from Oxygen Species Adsorbed on the Surface of Saccharides
BUNSEKI KAGAKU, 2005 多糖類の一種であるセルロースは，食品添加物として幅広く使用されているだけでなく，医薬品における賦形剤としてもはん用されている．糖類や穀物製品が自動酸化により極微弱化学発光（CL）を示すことが報告されているが，本研究では，セルロースと糖類に着目し，化学構造と発光の関係及びその発光メカニズムを検討した．9種類の糖を対象とし，極微弱化学発光法を用いて熱励起及び光励起によるCL強度及びCLスペクトルを測定した．また，半経験的分子軌道法（MOPAC）を用いて，糖類に対する酸素吸着のエンタルピー変化を計算し，発光メカニズムの理論的解明を行った．得られた知見より，糖類の極微弱化学発光には，糖類表面に吸着した酸素が関与していることが明らかになった．CL法は，自動酸化だけでなく ...
