“…The carbon-hydrogen (C-H) and oxygen-hydrogen (O-H) bonds are reported to strongly affect the absorption in the near-infrared region. 13 The low absorption in both the 1.3-and 1.55-m wavelengths, which are used in optical communications, is an important consideration in using these polymers for optical devices. It is also reported that the absorption due to C-H bonds can be reduced by the replacement of hydrogen in the C-H bonds to heavier atoms such as fluorine (F), chlorine (Cl), and deuterium (D).…”

We have developed novel lanthanide-cored supramolecular systems with highly efficient light-harvesting dendritic arrays for integrated planar waveguide-typed amplifiers. Er 3+ ions were encapsulated by the supramolecular ligands, such as porphyrins and macrobicyclics. The supramolecular ligands have been designed and synthesized to provide enough coordination sites for the formation of stable Er(III)-chelated complexes. For getting a higher optical amplification gain, also, the energy levels of the supramolecular ligands were tailored to maintain the effective energy transfer process from supramolecular ligands to erbium(III) ions. Furthermore, to maximize the light-harvesting effect, new aryl ether-functionalized dendrons as photon antennas have been incorporated into lanthanide-cored supramolecular systems. In this paper, molecular design, synthesis and luminescent properties of novel lanthanidecored integrated supramolecular systems with highly efficient light-harvesting dendritic arrays will be discussed.

“…52 Planar waveguide technology, in particular, is being researched as a solution to the traffic jam from long haul, oversea delivery of information to the short, metropolitan connection. 53 Polymers including polyacrylates, 54,55 polyimides, 56,57 polyethers, 58,59 and polysiloxanes 60,61 fill this requirement over inorganic counterparts because of their well-known optical properties, ease of processing, cost effectiveness, flexibility, toughness, tunability, and long term stability. However, in such systems CÀ ÀH vibration becomes the most significant role of attenuation in the near infrared (NIR) region.…”
