  Laser-initiated synthesis: 2,4,5,7-tetraiodo-6-hydroxy-3-fluorone as a visible photoinitiator

  摘要：

  The photophysical properties of a 2,4,5,7-tetraiodo-6-hydroxy-3-fluorone (TIHF) and its application as a visible-light photoinitiator to induce the reduction of organic halides by tri-n-butyltin hydride were investigated. Photobleaching quantum yields of TIHF by tri-n-butyltin hydride were determined in DMF-toluene (1:1) solution, and the absorption spectra provided evidence of ground-state complex formation. TIHF-initiated reduction of organic halides afforded clean products for alkyl, alkenyl, and aryl halides at ambient temperature and -30-degrees-C. The mechanisms of the initiation and the reaction are discussed.

  Polymerizable compositions are described containing colored polymerization indicators which confer a visible color on the unpolymerized compositions. Upon polymerization, the compositions exhibit reduced or eliminated color. The compositions can also change their opacity during polymerization. The compositions provide easy visual differentiation between the unpolymerized compositions and substrates on which the compositions are placed. The compositions are useful in clinical and laboratory applications such as those involving teeth, dental implants, orthodontic materials, artificial teeth and bones.

  所述的可聚合组合物含有有色聚合指示剂，可使未聚合组合物呈现可见颜色。聚合后，组合物的颜色会减弱或消失。在聚合过程中，组合物的不透明度也会发生变化。这种组合物在未聚合组合物和放置组合物的基底之间提供了简单的视觉区分。这些组合物适用于临床和实验室应用，例如涉及牙齿、牙科植入物、正畸材料、人造牙齿和骨骼的应用。
